Tidbinbilla notes for V185b\\


Config notes\\

  • Centre freq = 2280 MHz
  • Polarisation = RCP (IF1), LCP (IF2)
  • 1st LO = 2000 MHz
  • mix to 160 MHz into DAS
  • so 2nd LO for USB mix = 2280 - 2000 + 160 = 440 MHz
  • DAS profile = ti16s_f.pro
  • receiver configs:
    • DCC1: RCP → LNA2 (low noise path) → out (output 1 for SNT monitoring). So `SRLA2O1
    • DCC2: LCP → LNA1 (high noise path) → out\

Before the track\\

  • Tapes
    • get labels
    • load first set
  • Block 0 rack config
    • RCP → IF1
    • LCP → IF2
    • 2nd LOs 1 and 2 to 440 MHz
  • PCFS
    • sched files
      • fix timing
      • add source commands
    • modify PRC file
      • ND control
        • copy calon, caloff, toload, tosky from ndtest.prc
      • VFC patching
        • patch in S-band and set LOs to 272 MHz
      • S2 config
  • start DAS software
    • configuration ti16s_f.pro
    • adjust attenuators
  • telnet s2
    • check time
  • tidvsi
    • 203.5.58.205
    • check time
    • start disko
      • configure and start
  • xplot
    • on eac40: /opt/rmc/bin/xplot -rh pcfs40
  • start PCFS software
    • ssh ops@pcfs40
    • pcfsa-remote
      • S2, S-RCP, S-LCP, maintenance
    • start the schedule
    • configure VFCs with ifds and vclba

At start of track\\

  • NMC
    • Link
      • Build link with antenna and receiver, spacecraft 50 (VLBI), pass 0, two receivers.
    • antenna startup
      • in NMC:CTRL Connection Control:
        • AP D TRK (to show the track display)
          • Check for:
          • * delut ~ +291 ms
          • * models for encoder and position should be 3SPIG.AC1 and 3SCIB.SEM respectively
        • ap band s
        • ap move r=240
        • ap semn 3spig.ac1
        • ap semn 3scib.sem
        • ap radec 217.08656 -42.13415 (1424-418)
        • ap mode ac1
        • ap d sts (check all green. click on antenna to see brakes status)
        • ap trk (start the antenna)
        • (make safety page)
        • ap resm trk
    • start various blocks\
      • connection blocks → NDcontrol (Note PID)
      • connection blocks → UWVcontrol (Note PID)
      • connection blocks → what goes here?\
    • receiver config
      • us d smap
      • us d xmap
      • (double-click on dichroic to move it IN)
      • (configure with double-clicks)
      • D1 D CNF\
      • (select S band and [apply])
      • if fails, try SC 99
      • make carrier 2280 MHz
      • if fail to pick up correct LNA:
        • D1 set uwv reset
        • d1 set uwv srla2o2
      • D2 D CNF\
        • what goes here?\
      • configure noise diode
        • d1 d prf\
        • click on REC button in CNF window\
        • select 12.5K and frequency = on, apply
        • then enable/disable
        • to modulate
        • * 0.25 K, 20 Hz, 5s, enable
        • repeat for D2


  • boresight
    • manual offsets e.g:
      • ap po xel 0.1
  • PCFS
    • check atten levels
